Note: Older versions of the standard may have included ZDC3 (Alloy 2) but modern revisions focus on ZDC1 and ZDC2 due to better long-term dimensional stability.

| Property | ZDC1 | ZDC2 | |----------|------|------| | Tensile Strength (MPa) | ≥ 250 | ≥ 280 | | Elongation (%) | ≥ 1.0 | ≥ 0.5 | | Hardness (HB) | Approx. 80 | Approx. 95 |

JIS H 5114 primarily covers two major grades of zinc alloys for die casting, often referenced as: jis h 5114 pdf

The standard defines strict limits for copper (Cu), aluminum (Al), iron (Fe), nickel (Ni), and manganese (Mn). For example: : 8.0–10.0% Al, 1.0–4.0% Fe. : 8.0–10.5% Al, 2.5–5.0% Fe, 1.0–3.0% Ni. : 8.5–10.5% Al, 3.0–6.0% Fe, 3.0–6.0% Ni. Quality Requirements The standard mandates that castings must be of uniform quality

For fully validated engineering audits, active updates must be procured directly from the Japanese Standards Association Group Webdesk or authorized international aggregators. Note: Older versions of the standard may have

Never execute modern design phases using a withdrawn standard. If a drawing specifies an old designation like JIS H 5114 AlBC3 , update the specification to JIS H 5120 CAC703 or its international equivalent (e.g., ASTM B148 C95800 or EN 1982 CC333G ) to ensure procurement of valid, test-certified raw materials.

Aluminum bronze castings under this standard feature an intentional intermetallic structure. Aluminum acts as the principal alloying element (typically 8.0% to 11.0%), yielding high mechanical strength and scale resistance. Iron and nickel additions are tightly controlled to refine grain structures and inhibit self-annealing phases. Material Grade (Historical) Modern JIS Successor Grade Primary Application Focus Key Elemental Attributes Light to moderate structural components Excellent castability, balanced ductility AlBC2 Heavy-duty bearings, gears, wear plates High iron matrix, severe wear resistance AlBC3 Marine propellers, pump impellers Nickel-infused, premium cavitation limits AlBC4 High-stress aeronautical and marine hardware Maximum tensile capacity, low oxidation Key Technical Parameters Found in a JIS H 5114 PDF 95 | JIS H 5114 primarily covers two

If you are in a country with a national standards body (e.g., AFNOR in France, SNZ in New Zealand), they often have reciprocal agreements to sell JIS standards. Check with your local standards organization.
